Patent SE-8006388-L (SE)
Inventor: WEITMAN JACOB
IPC: B01D51/10
Filed: 1980-09-12
Abstract: A method for the treatment of contaminated and preferably heated air, so that it obtains a purity necessary for re-use and also a predetermined temperature and a predetermined relative humidity, simultaneously making possible a diminution of heat consumption. The air (A) is conducted against and about a first contact surface (5) while injecting water (6), as the case may be admixed with some additive, thereby separating out contaminations carried by the air and applying to the air a relative moisture of substantially 100%. The temperature of the air is lowered or raised by cooling or heating, respectively, via said contact surface, whereby the air attains a controlled temperature value (B). Then, said controlled temperature value is adjusted to a final value at the passage by a dry but properly heated contact surface (11), said air attaining the desired properly relative humidity (C).

Abstract: An agar gel consists of bundles of polysaccharide chains forming more of less parallel strings held together by hydrogen bonds. By shrinking the gel according to the invention, it has become possible to increase the dry content to 10-20 % by weight or more, with accompanying increase in strength and the possibility of using higher pressure in the separations. The gel is prepared by suspending water-containing gel particles in a liquid immiscible in water, impregnating them with macromolecules or microparticles, whereafter the water and the gel is replaced with organic solvent. When the solvent is evaporated, the volume of the gel is reduced and after dissolution of the macromolecules or microparticles, a strong gel skeleton remains. Adsorptionconducting groups can exist in the gel from the begining or be introduced during the preparation. The properties of the gel can vary greatly with the size of the cavities, the hardness of the gel skeleton, the cross linking and the adsorption-conducing groups, and the gel product thus has a very wide range of use for various separations.

Abstract: In a flexible control cable, for example a brake or clutch cable for motor vehicles, with a protective guide sheath and a force transmission element arranged therein for longitudinal movement, for example a steel wire cable, the protective guide sheath consisting of a wire spiral which is lined on the inside with a plastic tube and shrouded on the outside with plastic, the problem of coping with relatively large compressive forces in the sheath arises. In order to achieve the resulting object of preventing individual windings of the wire spiral from breaking out in the curved state of the control cable, the wire spiral (13) is firmly wound in spaced windings on the plastic lining tube (12) and the plastic shroud (14), which may be produced by injection under pressure, fills the spaces (15) between the windings and surrounding the spiral so that the lining (12) and the shroud (14) cohere between the windings. The invention may also be applied to a flexible feed tube, for example a welding rod guide tube, without a force transmission element arranged therein for longitudinal movement. <IMAGE>

Abstract: In cone crushers with a cone brake arranged between the crusher cone and the eccentric bushing and consisting of a torsion element fixed in the neck portion of the supporting and crushing cone and connected to an overrunning clutch arranged on the displacement piston in the cone shaft, the torsion element, when constructed as a wire cable, can be broken because of the high torsional and bending loads on the torsion element of the cone brake. On the other hand, the conventional torsion elements consisting of steel rods are relatively secure against breakages but are difficult to produce, insufficiently flexible, and entail high costs. These disadvantages are, however, eliminated according to the invention, where the torsion element, arranged between the neck portion (1) of the supporting and crushing cone (2,14) and the overrunning clutch, consists of a cable (3) which is externally surrounded at least partially by a reinforcing element (17). <IMAGE>

Abstract: A method of, and a system for, selectively delivering still television video with accompanying audio to home subscribers over a cable television system for advertising, promotional or educational purposes. A maximum number of home subscribers can interactively request presentations of their own choosing to be displayed on their home television sets. Only one standard television channel is required for transmission of still video with accompanying audio to serve 300 concurrent users. No equipment is required in the subscriber's home. The video is presented as still frames from one of a number of videodisc players, transmitted over one television channel during the appropriate time interval of 1/30th (or 1/25th) of a second. Such video frames, which may also contain overlaid graphics information, are uniquely addressed to a remote storage device. Unused bandwidth is used for the transmission of up to 300 discrete audio messages. The remote storage device identifies the appropriate video still frame, stores it, combines it with the corresponding audio message and conveys both to the home subscribers' television on a pre-selected channel. By uniquely addressing video frames to the remote storage device, either 30 (or 25) different video frames per second can be conveyed on one television channel to 30 (or 25) different remote storage devices for retransmission to home subscribers. Thus, if a home subscriber sees a given still video frame for 10 seconds, his remote storage device need not be updated for those 10 seconds, enabling the system to transmit 300 (10 secondsx30/second) different video frames to 300 other remote storage devices, thereby serving 300 concurrent users.

Abstract: Leaf (6) of a disc filter sector, consisting of a flow-permeable hub with flow-carrying ducts located therein, and of a screen fixed on the hub, which admits the filtrate but, e.g. retains the fibre cake on its surface. One drawback of the existing disc filters is that the fibre cake does not readily detach from the surface of the leaf (6) which results in a reduction of the capacity of the disc filter. This drawback is overcome in the invention by there being arranged, above the screen, on both sides of the leaf and on at least one leaf edge, a strip (7) projecting from the plane of the screen, in order to facilitate scraping the cake off the surface of the leaf (6) in the discharge phase. <IMAGE>

The spacing of the plates or said spacing and the length of the straight portions (14a, b) is so selected that the flow trajectories (17, 18) which are associated with the streamlines through said channel portion (1d) and which intersect the two most remote transitions (15a, 16b) between curved and straight portions in said channel portion (1d), or the two transitions between the curved portions of said channel portion (Fig 1), also intersect the channel axis (19) at such points (20, 21) that the length of the axis between the latter points of intersection is substantially half the length of the axis (19) in the channel portion (1d). <IMAGE>

Abstract: In a sliding roof or sliding lifting roof for motor vehicles, the lateral guide rails for the sliding guidance of the rigid cover and the roof frame carrying the same are entirely located below the fixed vehicle roof and are fitted closely adjacent thereto, so that neither the roof frame, nor the guide rails can reduce the free opening cross-section of the roof cutout releasing the cover following its opening. As the water channel for collecting the water penetrating via the marginal gap between the cover and the roof cutout edge is fixed only at a limited distance below guide rail, the overall height of the roof construction can be limited. As a result of the elastically deformable construction of the edge of the water channel facing the roof cutout, the guide parts of the cover or, in the case of the sliding lifting roof, the intermediate frame can pass in unimpeded manner through the elastically expandable gap between the roof cutout edge and the elastically deformable water channel edge to the guide rails.
